Lost time injury (LTI): Fall from height

The incident occurred when a senior ROV pilot technician was climbing down from the ROV hydraulic power unit (HPU) after cleaning the unit with another crewman acting as spotter and assistant. When making his final step down from the HPU, the injured person’s full body harness safety lanyard caught on one of the rigging points.

As the lanyard hung up, it prevented him from touching the deck with his final step from the HPU, causing him to swing into and make forceful contact with the LARS stowed transport post. The post protruded approximately 5 inches and is approximately 4 feet off the deck. He hit the post in the lower right back just below his right shoulder blade.

During the injured person’s descent, the other crewman had left the area to stow tools. He heard a loud bang and a scream. When he arrived back at the scene, he noted his colleague was suspended approximately one inch off of the deck, with toes just touching the deck. He helped him to the deck, and called the medic.

The injured person was taken to local medical facilities where he was diagnosed with rib contusion and given prescription drugs for pain. At a follow-up examination some days later the injured person’s duty status was changed to restricted duty with no bending, no climbing and no lifting of more than 5 kg. A further medical appointment was scheduled. Four days of lost time were incurred.

The company’s investigation revealed the following:

• Failure to follow the job safety analysis that had been established and reviewed prior to work starting.
  
  
  • The JSA identified that a ladder should be used; however, this ladder was not used for either ascent or descent.
    
    
  • The spotter was to remain in the work area during the performance of all tasks, but left to store tools during his colleague’s descent from height.
    
    
• Rushing to complete the job without consideration of hazards which included:
  
  
  • the injured person failing to check all conditions before descent from the HPU, and
    
    
  • the spotter leaving the area to store tools before his colleague was safely on deck.

The company noted that risk assessments and job safety analyses are generated and reviewed for employees’ safety, and should be read, understood and followed, otherwise employees and their colleagues can be placed at risk.
